Publishing Co-produce Objects
In a manufacturing plant, the same material can be used to produce different components of a product. Parts that are produced in a single production process can be put together as a co-produce object. One of these parts can be considered as primary, and the other parts as secondary. For more information, see Co-produce Object.
You can publish the co-produce object information in the Windchill Enterprise Systems Integration (ESI) response to a distribution target using Windchill ESI.
Windchill ESI lets you publish the co-produce object information that are created or changed within Windchill MPMLink to a distribution target. You can assign one or more distribution targets to a made from set object through Associate Distribution Targets option from the Actions menu or using Windchill loader. For more information on assigning a distribution target, see Associating Distribution Targets with Objects and Using a Loader to Assign Distribution Targets.
Windchill ESI passes the following co-produce object information to the EAI software components.
The following attributes of the MadeFromObject are passed:
• ObjectID
• Class — com.ptc.windchill.esi.MadeFromObject
• LastChangedBy
• Number
• DefaultUnit
• Name
• PartType
• Source
• State
• View
• Version
• Iteration
• PreviousVersion
• AssociatedEffectivityID
• Type — Coproduce
• TargetID
The following attributes of BOMComponent of the co-produce object are passed
• ObjectID
• Class — com.ptc.windchill.esi.BOMComponent
• PartNumber
• AssemblyPartNumber
• AssemblyPartID
• Quantity
• Unit
• LineNumber
• FindNumber
• AlternateItemGroup
• ComponentID
• IsChildPhantom
• IsPartConfigurable
• IsPartCollapsible
• AssociatedEffectivityID
• IsRawMaterial
• Usage
• Alternate
• Type
• Category
• Consumption
• TargetID
The following attributes of BOMHeader of the co-produce object are passed:
• ObjectID
• Class — com.ptc.windchill.esi.BOMHeader
• LastChangedBy
• Number
• Version
• Iteration
• EnterpriseVersion
• PreviousVersion
• Usage
• Alternate
• IsCADPhantom
• IsCollapsible
• AssociatedEffectivityID
• Type
• TargetPlant
• Quantity
• Unit
• AssociatedMadeFromObjectID
• IsAllocatedAsResource
• TargetID
In the ESI response, the co-produce structure is published as an alternate BOM for its primary part.
When publishing a process plan associated with a co-produce object, the process plan associated with the co-produce object is published as a process plan for the primary part of the co-produce. The part to process plan link is sent with the primary part instead of the co-produce object.
The following information is also published in the ESI response:
• Enterprise Data
• Plant Data
• Department Data
• Documents associated with the co-produce object
You can publish co-produce information using the following methods:
• Set State
• Change Notice
• Send to Distribution Target
• Co-produce associated with BOM, process plan, and resource structure for its primary part
 |
For SAP, co-produce information is consumed as an alternate BOM by setting the coproduce flags on material master and BOM components.

Persisting Consumption Information in SAP
The consumption information for the co-produce structure is persisted as Joint Production information at the SAP side on the co-produce primary part. SAP allows users to persist only one number (represented as a percentage value), called Equivalence Numbers in SAP, for each primary and secondary part of the co-produce structure.
The Category attribute in the CoProduceUsage BOM component indicates which consumption values are to be persisted in SAP for the given primary and secondary parts of the co-produce structure.
If the Category attribute has a value set to semifinished, the consumption percentage values are persisted for the respective primary and secondary parts of the co-produce structure.
If the Category attribute is set to semifinished for more than one CoProduceUsage BOM component with the consumption percentage values for the same primary or secondary parts of a co-produce structure, an exception “Multiple consumption values for any Primary or Secondary part for a Co-produce object are not supported.” appears from TIBCO business logic.
If the Category attribute has a value set to mounting, the consumption percentage values are not persisted for the respective primary and secondary parts of the co-produce structure.
You can view the joint production information that was persisted for the primary co-produce part in Material Master information in SAP using T-Code MM03. The joint production information is persisted on Material Master in SAP using a custom RFC /PTC/ZMATERIAL_COSTS_SPLIT_UPD.
The preference Publish Made From part consumption in a Co-produce BOM allows you to publish Made From part consumption by primary and secondary parts in a co-produce BOM.
Follow these steps to enable this preference:
1. Open the Preference Management utility. Click > > .
2. Select > > .
3. Set the preference Publish Made From part consumption in a Co-produce BOM as Yes to publish raw material consumption information in the ESI response.

• By default, this preference is set to Yes. Set this preference to No to disable publishing raw material consumption information in the ESI response.
• For incremental publishing, it is recommended that the unchanged BOM component links should be rendered in the ESI response to calculate consumption delta correctly.
